The Loudwater Mystery (1920)

Mr. Flexen drove back to the Castle, considering Hutchings carefully. There was no doubt that he was, indeed, badly frightened; but he had reason to be. Mr. Flexen could not decide whether he had worn the air of a guilty man or an innocent. He could not decide whether the butler had been too deeply absorbed in his own affairs to hear the snoring of Lord Loudwater as he went through the library. It was possible that Lord Loudwater was alive, asleep, and yet not snoring at the time. Snoring is often intermittent.
